    摘要: The present invention provides an electrophotographic apparatus which suppresses the unevenness of image density, even though the electrophotographic apparatus has no heater for an electrophotographic photosensitive member. For this purpose, the electrophotographic photosensitive member is arranged in the electrophotographic apparatus so that when the electrophotographic photosensitive member is equally divided into two regions in a cylindrical shaft direction, absolute values of a temperature dependence of photosensitive-member characteristics in the two regions are not the same, and when a region out of the two regions which has a smaller absolute value of the temperature dependence of the photosensitive-member characteristics is defined as a first region, and a region which has a larger absolute value of the temperature dependence of the photosensitive-member characteristics is defined as a second region, the change of a surface temperature of the first region becomes larger than the change of a surface temperature of the second region when an image is formed by the electrophotographic apparatus.
